Abstract: There is provided a bathtub apparatus capable of satisfactorily detecting an electrocardiographic signal even in a state where water is being discharged into a bathtub by a water discharge device. The present invention is a bathtub apparatus (1) including a bathtub main body (2), a water discharge device (8) that discharges water toward inside of the bathtub main body and is provided above a first inner wall surface (2a) forming a short side of the bathtub main body, and electrodes (4a, 4b, 4c) attached to the bathtub main body to detect an electrocardiographic signal of a bathing person, where the electrodes are arranged on an inner wall surface of the bathtub main body, and are arranged closer to the first inner wall surface than a position (P) where water discharged from the water discharge device hits a water surface of the water stored in the bathtub main body.

Abstract: A magnetic recording medium includes a non-magnetic substrate; a soft magnetic layer; a first seed layer; a second seed layer; an underlayer; and a perpendicular magnetic recording layer. The soft magnetic layer, the first seed layer, the second seed layer, the underlayer and the perpendicular magnetic recording layer are disposed on the non-magnetic substrate in this order. The first seed layer includes MoS2, hexagonal-BN, WS2, WSe2 or graphite. The second seed layer includes AlN having a hexagonal wurtzite type crystal structure. The underlayer includes Ru.

Abstract: Refrigerator (100) includes RFID tag (21) in which an appliance information is stored, product label (23) that indicates the appliance information, and a plurality of parts that configure refrigerator (100). In addition, product label (23) and RFID tag (21) are disposed on the same part among the plurality of parts. In this way, refrigerator (100) is provided, in which product label (23) and RFID tag (21) for identifying the individual home appliance are centrally managed and a mismatch between the appliance information items is prevented in advance.

Abstract: A refrigerator includes refrigerator body having a plurality of storage rooms, a plurality of doors that open and close the plurality of storage rooms, and RFID tag that performs proximity communication. In addition, RFID tag is provided on the uppermost door among a plurality of doors. In this way, a specific communication failure of refrigerator or dirt on mobile terminal which easily occurs due to the spilling of water or dirt at the time of taking food in and out of the refrigerator can be prevented, and thus, it is possible to provide refrigerator having a high reliability.
